What else can I help you with?
True or false The compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA?
It is true that the compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA. It is also known as Acetyl coenzyme A.
Burning coal produces the greenhouse gas carbon dioxide is this a false statement about the use of coal?
No, this is true. Coal is a fossil fuel which holds carbon which has been trapped underground for millions of years. When it is burnt the carbon dioxide is released where it adds to the greenhouse gases in the atmosphere.
When carbonic acid decomposes carbon monoxide is one of the products true or false?
False. When carbonic acid decomposes, one of the products is carbon dioxide, not carbon monoxide. Carbonic acid (H2CO3) breaks down into water (H2O) and carbon dioxide (CO2).
Carbon can only form ionic compounds true or false?
False. Carbon can form both ionic and covalent compounds. Carbon typically forms covalent bonds due to its ability to share electrons with other elements.
What following statements about acids and bases is false?
Acids add H+ ions to a solution. Bases add OH- ions to a solution.
Which statement is false regarding glycolysis?
Every step is irreversible.
What statements regarding the cell cycle control system is false?
A false statement regarding the cell cycle control system could be that it is completely independent of external signals. In reality, the cell cycle control system is heavily influenced by external signals, such as growth factors and DNA damage, that regulate the progression through different phases of the cell cycle.
What regarding control of the lac operon and lactose utilization in bacteria is false?
Bacteria preferentially utilize lactose as a carbon source.
What regarding the carbon atoms in a molecule and its functional groups is false?
One false statement could be that all carbon atoms in a molecule must be part of a functional group. This is incorrect, as some carbon atoms may simply be part of the molecule's backbone without participating in a specific functional group.
What is a false statement about regarding root-hairs?
One false statement about root-hairs is that they can sense gravity. It is a common misconception that gravity effects the direction of growth.
Does the carbon cycle involve an exchange of carbon between the atmosphere and geosphere only?
No, the carbon cycle involves the exchange of carbon between the atmosphere, biosphere (living organisms), geosphere (rock and soil), and hydrosphere (oceans and other water bodies). Carbon moves between these reservoirs through processes like photosynthesis, respiration, and weathering.
What statement most accurately describes the Magna Carta?
A common false statement about the Magna Carta is that it was signed by King John. This statement is false, because the Magna Carta was signed by Queen Elizabeth II at a ceremony at Runnymede in 1965.
Do The Krebs cycle produces NAD electron carriers and carbon dioxide true or false?
false. it produces ATP, electron carriers and carbon dioxide.
is this statement true or false BC?
If the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then "This statement is false" is true, making the statement false. But if the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then... It's one of the biggest paradoxes ever, just like saying, "I'm lying right now."
What of the following is a false statement with regard to the information in the field trip on prenatal exposure?
To determine which statement is false regarding prenatal exposure from the field trip, I would need the specific statements to evaluate and compare them against the information discussed. Please provide the statements, and I can help identify the false one.
True or false the main carbon cycle is conversion from carbon dioxide to living matter and back to carbon dioxide?
True. The main carbon cycle involves the conversion of carbon dioxide into living matter through photosynthesis by plants, which is then released back into the atmosphere as carbon dioxide through respiration and decomposition processes.
What is a false statement about wetlands?
A false statement about wetlands could be that they do not play a significant role in supporting biodiversity and ecosystem services. In reality, wetlands are highly diverse ecosystems that provide essential habitat for many species and play crucial roles in water filtration, flood control, and carbon sequestration.
